Code:

$('#my_tabs_id').select(function(event, ui) {
    $my_form = $('#my_form_id');
    var tag = '<input type="hidden" name="tab_target" value="' + $(this).tabs('option', 'selected') ' + "/>';
    $my_form.append(tag);
    $my_form.submit();

I've not tried that but it is along the lines of what you're looking for I think
